TRACK FOR SLIDING DOORS.

Specification of Letters Patent.

Patented J an. 29 1918.

Application filed June 25,1917. Serial No. 176,785.-

To all whom it may concern: V

Be it known that I, Gnones B. Kon'rzon, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Tracks for Sliding Doors, of which the following is a specification.

.My invention relates to tracks or runners for supporting and guiding sliding doors, windows and similar closures for display counters, cabinets and the like.

fine of the objects of my invention is to economize material in the construction of a track or runner of this character. Another object is the provision of'a device of this kind that may be readily stamped out of commercial forms of angle metal, that are purchasable in the open market, or from a flat blank of metal. Other objects are the provision of a track or runner constructed 1n the manner above mentioned that is dependable and effective in its operation, economical to manufacture, and comparatively simple in its structure.

Other objects and advantages will be ob vious to others after an understanding of my invention is had, and I prefer to accomplish the divers objects by the means and in the manner hereinafter fully described, reference being had to the accompanying drawings that form a part hereof In the drawings- Figure 1 is a perspective view of a short length of track made in accordance with my invention and drawn to an enlarged scale.

Fig. 2 is a top plan thereof, and

Fig. 3 is a vertical transverse section thereof on line 33 of Fig. 2.

Fig. 4 is a transverse section of a modified form of my invention.

Fig. 5 is a fragmentary top plan. of the modification shown in Fig. 4:.

Referring to the drawings, it will be observed my invention comprises a length of metal of substantially right-angle or l.- shaped cross-section, the upper edge of the vertical flange 5 whereof affords the tread upon which the sliding door, window or other structure is supported and guided, while the horizontal flange 6 provides the base or support for said tread portion and is provided with a desirable number of holes 7,

through which screws are passed for securing the track in position in its proper place.

Tracks of the type thus described have been used for the same purpose for which have designed my improved track, but it has been found that the weight of the struc-- ture supported thereby has a tendency to and actually does strain the horizontal or base flange for the reason that the weight is entirely along one edge of flange 6 and there fore is not evenly distributed, hence the opposite edge is pried up and loosened from the supporting structure. In order to over come this inherent objection, I prefer to punch or stamp out suitable portions 8 of the metal of the vertical flange 5 and bend them laterally thereto so that they will lie in substantially the same plane with the base or horizontal flange 6, as shown in Figs. 1, 2 and 3. These stamped out portions 8 provide lateral lugs or feet that extend outwardly from the flange 5 upon the side thereof opposite the base flange 6, and suitable holes 9 are formed in said lugs through which screws may be passed to secure the track rigidly in position.

In lieu of stamping or punching out the lugs 8 from the metal forming the tread flange 5, said lugs may be readily stamped or punched out of the base flange 6, as shown a in Fig. at, and bent under until they are disposed at substantially right angles to the vertical track flange and in alinement with the base flange, in which event the screw holes 7 will necessarily have to be staggered with relation to the lugs, which will not detract from the effectiveness of the device.

It will be observed that the lateral lugs project from the side of the track opposite the base flange and thus act as a brace and prevent the tipping of the track by relieving the screws in holes 7 of approximately one L-shaped cross-section, and lateral bracing lugs starnped out of one of the flanges of said strlp and extended in alinement with r the horizontal flange thereof.

7 other of said flanges vertically to provide the 7 comprising a strip of inetal bent mediate its longitudinal edges, to provide adupri' h't flange and a lateral H flange at substantially right angles thereto whereby a track base "of substantially L-shap ed cross-section is pr0- vided, and lateral bracing lugs stamped out of the upright flange and extended in alinenient with the horizontal flange thereof.

4. A track 01' runner for sliding doors comprising a strip of metal of substantially L-shaped cross-section, and lateral bracing lugs stamped out of the vertical flange of said strip and extended into alinement with the horizontal flange thereof whereby a structure of substantially T-shaped crosss'ecti'on is provided t the locations of said lugs. r
